Background: Job safety analysis (JSA) is a popular technique for hazard identification and risk assessment in workplaces that has been applied across a wide range of industries. This systematic review was conducted to answer four main questions regarding JSA: (1) which sectors and areas have used JSA? (2) What has been the aim of employing JSA? (3) What are the shortcomings of JSA? (4) What are the new advances in the field of JSA? Methods: Three main international databases were searched: SCOPUS, Web of Science, and PubMed. After screening and eligibility assessment, 49 articles were included. Results: Construction industries have used JSA the most, followed by process industries and healthcare settings. Hazard identification is the main aim of JSA, but it has been used for other purposes as well. Being time-consuming, the lack of an initial list of hazards, the lack of a universal risk assessment method, ignoring hazards from the surrounding activities, ambiguities regarding the team implementing JSA, and ignorance of the hierarchy of controls were the main shortcomings of JSA based on previous studies. Conclusion: In recent years, there have been interesting advances in JSA making attempts to solve shortcomings of the technique. A seven-step JSA was recommended to cover most shortcomings reported by studies.

Objectives : This study was carried out to determine whether Juglandis Semen herbal acupuncture (JSA) exerts the protective effect against toxic agent-induced live. cell damage. Methods : The cell damage was estimated by measuring lactate dehydrogenase (LDH) release, and lipid peroxidation was estimated by measuring maiondialdehyde (MDA), a product of lipid peroxidation, in rabbit liver slices. Results : When tissues were incubated with 0.5 mM Hg for $10{\sim}120\;min$, LDH release and lipid peroxidation were increased as a function of incubation time, and these effects were significantly prevented by addition of 0.1% JSA. Hg increased LDH release and lipid peroxidation in dose-dependent manner over the range of $0.1{\sim}l\;mM$ concentrations, which were reduced by 0.1% JSA. When tissues were treated with 0.5 mM Hg in the presence of $0.05{\sim}l\;%$ JSA, LDH release and lipid peroxidation induced by Hg were prevented by JSA in a dose-dependent fashion. JSA at 0.5 and 1% prevented completely effects of 0.5 mM Hg. When tissues were treated with 0.5 mM Hg for 60 min, LDH release and lipid peroxidation were increased, which were significantly prevented by addition of 0.1 % JSA. tert-Butyl hydroperoxide (tBHP) increased LDH release and lipid peroxidation, which were significantly reduced by 0.1 % JSA. Such protective effects were similar to those of N,N'-diphenyl-p-phenylenediamine (DPPD), a potent antioxidant. When tissues were treated with 0.5 mM Hg, activities of catalase and glutathione peroxidase were inhibited, and glutathione content was also reduced. Such effects were prevented by JSA, but not by DPPD. JSA prevented Hg-induced morphological changes. Conclusions : These results indicate that JSA exerts the protective effect against liver cell injury induced by toxic agents through antioxidant action, and this effect may be attributed to an increase in activities of endogeous anitoxidant enzymes and GSH content. However, antioxidant effect of JSA is different from that of a well-known potent antioxidant DPPD.

Objective : The present study was carried out to determine if Juglandis Semen Aquacupuncture(JSA) exerts beneficial effect against the urine concentrating defect induced by glycerol injection in rabbits. Methods : In order to test the effect of JSA, rabbits were acupunctured with $0.5m{\ell}$ of 1%JSA for 7days at both sides of $Sh{\grave{e}}ns{\bar{u}}$(BL23) before the glycerol injection. The other animals were pretreated with an equal volume of saline instead of JSA. Results : The urine flow was reduced, but the urine osmolality was significantly lower than the basal period in glycerol-injected animals, indicating that glycerol causes the urine concentrating defect. The fractional excretion of Na and K was increased in glycerol-treated animals. The Free-water clearance and fractional water excretion(V/GFR) were increased in animals treated with glycerol. Conclusion : These results indicate that glycerol injection resulted an impairment in the urine concentrating ability in rabbits. Such changes were prevented by JSA. JSA may be used as a method to treat and prevent glycerol-induced acute renal failure.

Lactobacillus species have been shown to enhance intestinal epithelial barrier function, modulate host immune responses, and suppress the growth of pathogenic bacteria, yeasts, molds, and viruses. Thus, lactobacilli have been used as probiotics for treating various diseases, including intestinal disorders, and as biological preservatives in the food and agricultural industries. However, the molecular mechanisms used by lactobacilli to suppress pathogenic bacterial infections have been poorly characterized. We previously isolated Lactobacillus plantarum JSA22 from buckwheat sokseongjang, a traditional Korean fermented soybean food, which possessed high enzymatic, fibrinolytic, and broad-spectrum antimicrobial activity against foodborne pathogens. In this study, we investigated the effects of L. plantarum JSA22 on the growth of S. Typhimurium and S. Typhimurium-induced cytotoxicity by stimulating the host immune response in intestinal epithelial cells. The results showed that coincubation of S. Typhimurium and L. plantarum JSA22 with intestinal epithelial cells suppressed S. Typhimurium infection, S. Typhimurium-induced NF-κB activation, and IL-8 production, and lowered the phosphorylation of both Akt and p38. These data indicated that L. plantarum JSA22 has probiotic properties, and can inhibit S. Typhimurium infection of intestinal epithelial cells. Our findings can be used to develop therapeutic and prophylactic agents against pathogenic bacteria.

As asbestos-containing buildings are getting older, asbestos deconstruction works are increasing. As a result, accident risks such as falls, cuts, electric shocks, and suffocation are increasing. Existing studies are mostly about health management and institutional policy research and there is little research on work risk. So workplace risk assessments that are easily applicable in the field are required to be applied. Sealing is the first process of asbestos deconstruction and is the first step to ensure worker's safety. Job Safety Analysis(JSA) and Checklist were used to identify the risk factors and to calculate the level of the risk. By comparing the two risk assessment tools, it was figured out that the JSA is appropriate for the initial process and change of work procedure while Checklist is appropriate for repetitive work. Because the sealing process is sort and simple, it is unlikely to cause serious injury. But since the risk of falling and cuts are exist, safety education and supervision are necessary to maintain a safe working environment.

Offshore drilling units have a very dangerous working conditions due to the harsh working environment of the ocean and the high possibility of fire or explosion. This study would identify the hazards that emerge from the marine environment in the operation and maintenance phase of offshore drilling units and show how these hazards can be reduced through risk assessment/management. Various risk reduction and management measures were first reviewed, and Job Safety Analysis (JSA) was selected as the risk assessment technique of this study. In order to understand the characteristics of offshore drilling operations, accident statistics of onshore and offshore drilling were analyzed and compared with each other, and major risk factors for offshore drilling were derived. The jobs in which offshore drilling accidents occur more frequently than onshore drilling was analyzed as the job of fastening, transporting and moving pipes and various materials. This result is due to the limited space of the ocean and the work environment that is prone to being shaken by wind, waves and ocean currents. Based on these statistical results, the job of picking and making up drill pipes was selected as a high-risk job, and JSA was performed as an example. A detailed safety check procedure is proposed so that workers can fully recognize the danger and perform work in a safe state that has been confirmed.

본 연구는 2000년대 등장한 다수의 분단영화 중에서 간첩영화와 남성 버디무비의 성격을 띤 세 편의 영화<공동경비구역 JSA>(박찬욱, 2000), <의형제>(장훈,2010), <공작>(윤종빈, 2018)을 중심 텍스트로 하여 남북 남성주인공의 관계 변화와 주요 공간적 배경의 차이와 상징성이 갖는 의미를 고찰하는데 목적이 있다. <공동경비구역 JSA>는 2000년대 분단영화의 서막을 연 작품으로 이전과는 다른 차원의 남북관계를 제시한다. 남북한 병사들이 비무장지대에서 만나 친구가 되고 북한군 초소에서 어울리는 것이다. <의형제>는 북에서 버림받은 남파 간첩이 생계형 간첩으로 살아가며 국정원에서 버림받은 전직 남한 요원과 동업을 하는 이야기다. 친구에서 형제로 나아간 남북관계에 대한 전망은 <공작>에 이르면 동반자의 관계로 성숙한다. 10년 정도의 시차를 두고 나온 세 영화들은 지난 20년 동안 이루어진 남북관계 변화 자체도 담고 있지만 남북관계에 대한 사회적 인식의 변화를 보여준다는 의미가 있다. 각기 다른 시기 다른 감독이 연출한 작품들이지만, 궁극적으로 통일서사를 지향한 행보를 읽을 수 있다.
